Paraguay recently adopted permanent Daylight Saving Time. Less than a year later, citizens demand permanent Standard Time, to restore morning sunlight.

Video of the international student at Tufts being arrested by "federal authorities" in Massachusetts has been released and it's terrifying.
They're not even uniformed officers. Just secret police thugs in hoodies and masks.

Digital twin is a term that means ten different things to ten different people. For our app, Arcashift, "sleep + circadian digital twin" means:
- we have a system of differential equations that acts like your brain acts in response to light and other stimuli
- and also a cute character builder
- we have a system of differential equations that acts like your brain acts in response to light and other stimuli
- and also a cute character builder
Our CEO, Olivia Walch, describes Arcascope’s digital twin as a crash test dummy for your sleep: simulating thousands of outcomes to give you the best sleep, energy, and circadian rhythm strategies. Read more on our website: arcascope.com/what-a-sleep... #CircadianRhythms #DigitalTwin
What a Sleep and Circadian Digital Twin Can Do For You
But a digital twin for sleep and circadian rhythms— specifically, the digital twin we’ve built at Arcascope, can add value to your life. That’s what this blog post is about.
